This is a very interesting article about why the naked mole rat can’t feel pain from acid burns. Apparently it was already known that they don’t feel the pain; their hypothesis about why it happened—that the acid sensing ion channels that tell neurons to transmit pain would be missing—was not true.
I recently found this very interesting documentary, called ‘Forks over Knives’, that deals with the idea that much of our modern health problems can be solved by changing our diets. This in itself is, of course, not a revolutionary idea—most of us are quite aware of what we need to do to stay healthy. (That we don’t actually do it is another matter entirely!)
What piqued my interest (and great dismay) was some of the views in the documentary—were some of the ideas that I currently have so wrong? And the theses were from respected doctors, who seemed to have done quite a bit of research, and extensive research at that, in coming up with their ideas!
Being conscious of our hygiene is a good thing, of course. But is it possible to overdo our hygiene routines for our own good? Have you noticed how more and more people use sanitizing hand wipes, or antibacterial hand soaps? Their function, of course, is to ‘wipe out’ all the bacteria around you—but is that always a good thing?
I’ve always had my theories, but now there’s actual evidence—it’s probably not a very good thing on the long run.
I had not heard of the Abydos carvings before. But then we went to Egypt, and it turned out that my Dad had requested that Abydos be put on the schedule—even though it wasn’t a ‘usual’ tourist destination. (I still don’t know whether he’d come across these specific carvings as a reason to go there. Baba, will you leave a comment if you read this? :))
But the carvings were quite amazing. There they were—a few of them adjacent to each other, each apparently depicting something we’d recognize as a modern (or future) means of air travel. (I have my own photos, but it’s easier to link to photos online.)
Steve Jobs passed away today. 😔
I’ve only seen him as a public figure, of course, but I was, and will remain, a fan. I’ve admired him greatly, not just for the company he built, but for how he conducted his business—well, for the things he said and did publicly, at any rate.
A straightforward, honest man who played extremely hard when running his company, but who made sure he did the right thing all the same.
Rest in Peace, Sir. Your legacy will live on, and will hopefully inspire the next generation of visionaries.

So, I’ve defended my Ph.D. Preliminary Exam (phew), and what lies ahead are the defense of my thesis proposal, and the final Ph.D. Dissertation Defense, of course.
Does this mean I can now call myself a ‘Ph.D. Candidate’, as opposed to a Ph.D. student? Is there a difference in connotation? I’m not really sure about the protocols involved.
If you happen to know the norms (or lack of them), leave a comment, will you?
A composite image created by combining data from the Chandra X-Ray Observatory and the Hubble Space telescope, this is a stunning image of two galaxies colliding. Both of them are spiral galaxies, and they are on the verge of a collision—with their disks oriented at 90 degrees to each other!
Well, “on the verge” is in galactic time scales, which means they’ll collide in a few million years. And considering that this is 450 million lightyears away from us, the event has already occurred—we just haven’t seen it yet.
A detailed description of the image is present as a caption with the photo itself. Go see it!
To the modern web user, passwords are usually a nightmare, especially with the modern trend of “your password must contain every possible category of keys”. Well, how effective is that sort of thing?
We’ve always wanted to fly, haven’t we? We’ve watched the birds in the sky, and thought, “Wish we could fly—just like them!” We’ve succeeded; we’ve built out flying machines; we’ve flown in the air.
But not like a bird.
The way a bird flies is quite complex, and difficult to implement in human flight. We’ve devised alternate methods—jet engines and rigid wings. But finally, technology and mathematics have caught up, and we have a robot that flies just like a bird—by flapping its wings!
